respectively attached to the upper innercorner portions of the curtains.

i My present invention relates to improvements in the cord guides that are located in the ends of the rod; and one of the 'objectsof the invention is to provide improved cord guides which may be telescoped withinthe ends of the curtain rod and may be readily withdrawn therefrom, when required, with out requiring any fastening devices. Another object is to provide an improved cord guide comprising a U-shaped frame and sheave or sheaves mounted therein together with a stop device on the frame which,

' through abutment against the end of the rod,

prevent the frame from being drawn in-' wardly under the pull on the cord. Another object is to provide an improved frame structure designed to facilitate the entry of the cord onto the sheaves.

The. invention, in one practical and improved forrn inwhich the same may be embodied, is illustrated in the accompanying drawings in whichv Fig. 1 is a front elevation of a curtain fixture showing the same mounted on a window frame. i

Fig. 2 isan enlarged horizontal longitudinal section, taken on the line 22 of Fig. 1, and broken out between its ends.

Fig. 3 is a vertical transverse section taken on the line 3--3 of Fig. 2.

Fig. 4 is a perspective elevation of the sheave carrier and sheave located at the left hand end of the rod in Figs. 1and'2.

Fig. 5 is a perspective elevation I of the sheave carrier and sheave located at the right hand end of the rod in Figs. 1 and 2.

In order that the relation of my improved cord guides to the other parts of a draw cord curtain fixture may be clearly understood,

I have, in the accompanying drawings, illustrated a form of curtain rod and master and follower slides by which the curtains are sus pended that are well adapted for cooperation with the improved cord guides forming the subject matter of the present invention; but it will be understood that the specific details of the rod and slides are in no wise essential to the present invention.

Referring to the drawings, 10 designates each of a pair of straight hollow curtain rod sections that are supported at their outer ends on brackets 11 and at their inner or meeting ends are rigidly connected and supported by an internal hollow splice 12; The rod herein shown is of a generally flat or C-type, but

is modified by. being made of somewhat greater width, and the top and bottom walls of the rod arepressed inwardly in the form of hollow longitudinal ribs 13, as shown in Fig. 3. These ribs create, in effect, a double or twin channel rod consisting of an outer or wider channel 14 and an inner or somewhat narrower channel 15. The rear wall of the rod has the usual central longitudinal slot of rods of the Ctyp'e, and in the rear channel 15 are mounteda group of curtain suspension slides, including a pair of master slides 16 to which the inner upper corners of the curtains C are attached, and a group of follower slides 17. The form of rod herein shown forms in part the subject matter of an application filed concurrently herewith, Serial No. 454,245; and the slides themselves form the subject matter of another application filed concurrently herewith, Serial No. 454,246. Since the structural details of the rods and slides are not concerned with the present invention, specific description thereof is not necessary.

At 18 isshown the usual draw-cord, which consists of a long loop, the twin limbs of which extend through the hollow rod, a bight of the loop passing over a guide sheave mounted in one endof the rod, and the two limbs passing over and extending downwardly from a pair of guide sheaves mounted in the opposite end of the rod, as usual in draw curtain fixtures of this type.

Describing now the improved cord guide which cooperates with the bight of the cord loop, and referring mainly to Figs. 2 and 4, this comprises a U-shaped sheave carrier or frame, the parallel flat side walls 19 of which are connected at their inner ends by an integral bridge 20. In and between the side walls 19 is journalen the sheave 21, and the outer end of one of the side walls 19 is formed with a laterally bent stop flange 22. As shown in Fig. 2, this sheave carrier and sheave is telescopable into one end of the front channel 14 of the curtain rod, the stop flange 22 abutting against th front wall of the rod, and thus holding the sheave carrier in place against the inward pull of the cord when the curtains are operated.

The sheave carrier and sheave at the opposite or right hand end of the rod is shown in detail in Fig. 5 and in horizontal longitudinal section in F i g. 2, and also comprises a generally U-shaped sheave carrier, the parallel fiat side walls 23 of which are connected along one longitudinal edge thereof (the bottom as herein shown) by a bridge 24:. In and between side walls 23 are journaled outer and inner guide sheaves 25 and 26 respectively, the outer sheaves 25 being located sutliciently higher than the inner sheave 26 to permit the upper limb of the cord which passes over the sheave 25 to clear the lower limb which is guided over the sheave 26. One of the side walls 23 is severed transversely at a point be tween the two sheaves and bent outwardly to form a stop 27 which, as shown in Fig. 2, abuts against the end of the rod and prevents the sheave carrier from being displaced inwardly under the pull of the cord. This forms a transversely disposed opening or slot 27 in the side wall, through which one limb of the cord may be passed sidewise onto the inner sheave 26; and the same side wall is cut away beyond the outer sheave 25, as shown at 27 to permit the other limb of the cord to be passed sidewise onto the sheave 25. This construction avoids the threading of the cord lengthwise through the sheave carrier. The bridge portion 24 of the sheave carrier is, of course, cut away below the outer portions of the sheaves 25 and 26 to permit the limbs of the cord to depend therefrom as shown in Fig. 1.

From the foregoing it will be seen that both of the sheave carriers above described are insertible within the ends of the rod by a simple sliding movement, and may be similarly withdrawn. The presence of the stop devices thereon abutting against the ends of the rod prevents the necessity of employing any fas toning or locking means for securing the sheave carriers in the rod. This is of particular advantage in connection with the sheave carrier occupying the left hand end of the rod, for this reason. If a given length of rod with which the cord, slides and sheave carriers have already been assembled, is

found to be too long for a given installation, the sheave carrier can be simply pulled out and the bight of the cord passed outwardly through the slot in the rear of the rod, the rod then cut off to the proper length, and the sheave carrier again inserted, without the necessity of removing or dismantling the other equipn'ient of the rod. The same thing an be done at the opposite end of the rod in case the latter is to be shortened at that end. The only strain tending to displace the sheave carriers from normal working position is an inward strain caused by a pull on either of the depending liml s of the cord; and obviously this inward strain is resisted by the stops on the sheave carriers in abutment with the ends of the rod.

I claim:
